Recently, Back Bay Social Club took its bar program up a notch by deciding to debut a barrel aged cocktail, a play on the classic scotch-based cocktail called the Blood and Sand. Instead of using the dark liquor, though, they swapped in Knockabout gin from Gloucester-based Ryan & Wood Distillers. While the cocktail is currently in the midst of aging (the photo above is of the cocktail two weeks in), it’ll be ready to quaff at a release party in about a month (the date is still T.B.D.). In the meantime, however, there are several other bars in town giving their booze the barrel-aged treatment—check them out in our roundup ahead.

Temple BarThis Cambridge spot offers three different cocktails that are all aged for 50 days in a used whiskey barrel from Tuthilltown Distillery and are served on the rocks for $11 apiece. Try the Red Sky, a mix of El Dorado three-year-old rum, cynar, lillet, and grapefruit essence. Availability is limited due to the aging process. $11/person, Mon-Fri, 5pm-1am; Sat-Sun: 11am-1am, 1688 Massachusetts Ave., Boston, 617-547-5055,www.templebarcambridge.com.

DrinkThe bar component of the Barbara Lynch empire is well-known around town for its handcrafted cocktails. You can get The Martinez for $11, which is a mix of rich, dry, barrel-aged Ransom Old Tom, Cinzano Rosso vermouth, Luxardo Maraschino liqueur, and a dash of Jerry Thomas Decanter bitters, polished off with a spritz of lemon oil. Not too shabby. $11/person, Mon-Sun 4:00pm-1:00am, 348 Congress St., Boston,, 617-695-1806, drinkfortpoint.com
